✦ Synopsis

The Ray-X sponges, which are now available, incorporate a barium sulfate insert that is permanently fused to the gauze and detectable under X-ray.

"Occasionally, it is necessary for an exploratory re-operation to determine whether or not a sponge is present," the company said. "Now it is possible to make positive diagnosis of such a situation, without re-operation, by use of Ray-X sponges."

Parke-Davis pointed out that the X-ray detectable insert is dark in color to distinguish Ray-X from ordinary sponges. The barium sulfate insert does not deteriorate and is detectable for a long period of time.

Produced at Parke-Davis' Bay Division, Bridgeport, Conn., the sponges "are soft, non-toxic, pliable and non-abrasive with all cut edges folded in," the pharmaceutical firm said. Ray-X sponges can be sterilized in the usual manner, and no special X-ray techniques are required when using the sponges.
